Cooley Celebrates 10th Anniversary in London

London – 12 May 2025 – Cooley is celebrating 10 years in London, having opened its office in the city in 2015. Since launching, the firm has nearly doubled its number of lawyers in London and achieved its goal of becoming a go-to advisor for high-growth life sciences, technology, and other disruptive and innovative companies, along with their investors. Cooley also launched a Brussels office in 2019 to further support the needs of its global client base.

“Our London office is second to none advising the most cutting-edge companies and attracting some of the market’s brightest talent in London and across Europe,” said Rachel Proffitt, partner and CEO of Cooley. “Expanding our London and European presence has long been a key component of our growth strategy, and I am very excited about the opportunity ahead.”

“We are hugely proud of our success story in London and the incredible work of the team,” said Claire Keast-Butler, co-partner in charge at Cooley London. “London is firmly established as the preeminent European centre for the life sciences and technology industries, and as the law firm at the forefront of this ecosystem, we are very excited about what we can achieve over the next 10 years and beyond.”

“With artificial intelligence and other highly sophisticated technologies, the pace of innovation is increasing at a meteoric rate, but at the same time the world is becoming an ever more complex place for high-growth disruptors,” said James Maton, co-partner in charge at Cooley London. “Our clients turn to us to help them found, grow and scale, mitigate regulatory risks and legal challenges, and resolve their disputes because of our deep sector and global experience. This is a real differentiator for us in the London legal market.”

In 2024, Cooley announced the addition of six market-leading partners: Angus Miln, Ali Ramadan and Helen Pantelides (emerging companies and venture capital); Jenny Davies (life sciences partnering and licensing); Bryony Hurst (data litigation); and Mark Simpson (contentious antitrust and competition). Promoting star internal talent also is central to Cooley’s strategy, and nearly a third of the firm’s 34 London partners were promoted from within.

Cooley’s success in London also is reflected by the firm’s multiple awards – including London Office of the Year, twice (British Legal Awards); International Firm of the Year (The Lawyer); US Law Firm of the Year (Legal Business Awards); Transatlantic Capital Markets Team of the Year and Transatlantic Litigation Team of the Year (Law.com); European Competition or Antitrust Team of the Year (The Lawyer’s European Awards); and multiple LMG Life Sciences EMEA Awards, including Venture Capital Firm of the Year and four Impact Deals of the Year in 2024.

In addition, Cooley is consistently ranked as a venture capital industry leader by Chambers and The Legal 500, as well as being the #1 law firm in the US and globally for representing companies in venture capital financing deals (PitchBook), the #1 venture capital law firm for biotech and pharma venture financings for the past decade (PitchBook), and the #1 law firm for European foreign private issuer US initial public offerings since 2016 (Deal Point Data, 2023).
